SCYTH E-SNATH FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 711,558,,dated October21, 1902.

Application filed January 3, 1901. Serial No. 41,964. (No model.)

To all whom it may concern:

Be it known that I, RoBERrB. ED'wARDs, a citizen of the United States,residing at Worcester, in the county ofNVorcester and Commonwealth ofMassachusetts, have invented a new and useful Improvementin Scythe-SnathFasteners, of which the following is a specification, accompanied bydrawings forming a part of the'same,vin which Figure 1 represents theslabbed end of a scythe-snath to which the scythe is attached. Fig. 2 isa central longitudinal sectional view through the end of thescythe-snath on line 2 2, Fig. 1. Figs. 3, 4, and5 represent,respectively, the pivoted plate, clamping-bolt, and flanged washer of myimproved scythe-snath fastener detached from the scythe; and Fig. 6 is atransverse sectional View on line 6 6, Fig. 1.

Similar reference-letters refer to similar parts in the different views.

My invention relates to that portion of a scythe-snath fastener by whichthe shank of the scythe is adjusted on the snath so as to vary theposition of the scythe; and it consists in the construction andarrangement of parts hereinafter described, and set forth in the annexedclaim.

Referring to the drawings, A denotes the end of a scythe-snath slabbedat one side, as at B, and provided on its end with a ferrule C andhaving an eyebolt D,- these parts being of the usual form ofconstruction in snaths now in common use. Resting upon the slabbedsurface Bis a plate E, provided at one end with a spurv F, projectingfrom its under side and held in a hole F in the scythesnath, forming apivot for the plate. The plate is provided with one or more openings Gto receive the usual lug on the shank of the scythe and an elongatedopening H, concentric with the spur F, to receive a clamping bolt I,having a head I and carrying a nut I and Washer I Projecting from theunder side of the head I and on diametrically 0p-' posite sides of thebolt are teeth J J, preferably triangular in their cross-section andadapted to engage a series of radial teeth K on the upper side of thepivoted plate E and on its surface which is adjacent to the elongatedbolt-opening H. Recessedin the snath is a sleeve L, having a. flange L,with its upper surface flush with the slabbed side B of the snath. Thesleeve L fits tightly within the snath and surrounds theclamping-bolt I,and its flange L forms a-bearing-surface for the under side-of thepivoted plate E. The plate E; as shown in the drawings, is providedwith'two openings G G for the scythelug, a certain adjustment ofthescythe being obtained by moving thelug from one opening to the other.Another and finer adjustment of the scythe is secured by releasing theclamping-bolt I and swinging the pivoted plate E to bring a new tooth onthe plateinto engagement with the teeth J on the bolt-head.

I am aware that it is not new to adjust the scythe by means of a pivotedplate held in any position by a clamping-bolt, and I do not claim suchbroadly.

What I claim as my invention, and desire to secure by Letters Patent,is-

In a scythe-fastener, the combination with a scythe-snath having aslabbed side and an eyebolt for receiving the shank of the scythe of asocket-plate provided with an opening midway between its ends for thelug of the scythe-shank, said plate having at its end nearest saideyebolt a cylindrical projection on its under side entering'a socket inthe snath and forming a pivot for said socketplate, an elongated openingcurved concentrically with said pivot in the end of said socket-platefarthest from said eyebolt for an adj usting-bolt, radial teeth on theupper surface of said socket-plate and adjacent to saidcurved opening,an adjusting-bolt having teeth beneath its head to engage said radialteethand a flanged sleeve recessed in "the snath inclosing saidadjusting-bolt and having its flange flush with the slabbed side of thesnath and bearing against the under side of said socket-plate,substantially as described.
